My Equinox 2013 had Yaw sensor replaced and reprogrammed but then began to drive erratically after. It has had 2 Yaw sensors and stability trak light stays on. It went off but then went back on and drove veering left. I have only had car 3 years and have never had such issues! Debating contacting Lemon law as cannot afford thousands of $ to repair and cannot put my daughter and my safety in jeopardy and have read numerous others with my same issue. And I still have car payments!
